https://wccftech.com/amd-will-now-support-virtual-nmi-vnmi-on-zen-4-cpus/ > On Thursday, AMD launched an open-source patch for the Linux kernel that would enable Virtual NMI or Non-Maskable Interrupt support on their Zen 4 CPUs. This particular feature for the processor in Linux OS is something rival Intel has supported with their CPUs for well more than the past decade. > VNMI support allows for the CPU ID to detect the feature, but due to the severely late release from AMD, it is possible that the company has chosen to not initiate it fully until the new Zen 4 architecture later this year.
